Reaction Steps

2-Methyl-benzothiazol-5-ylamine (32 mg, 0.2 mmol) and bromoacethyl bromide were added to a suspension of (N,N-diisopropyl)aminomethylpolystyrene resin (170 mg) in anhydrous TBF (2 mL) and the reaction mixture was shaken for 4 h at ambient temperature. The resin was then filtered off. 1H-benzoimidazole (35 mg, 0.3 mmol) and potassium tert-butoxide (0.36 mL of 1 M solution in THF, 0.36 mmol,) were added and the mixture was stirred at 55° C. for 24 h. The crude product was purified on a preparative LC/MS (XTerra C8 column 19×100 mm, 0.1 M aqueous NH4Ac/CH3CN). The pooled to fractions were lyophilized to afford 4 mg (6%) of the title compound. Calculated for C17H14N4OS m/z: 322.39, found 323.0 [M+H]+.
